7/7 Finally, I’ve gotten some comments suggesting this is targeted at Amazon to force them to sell e-books via in-app purchase in the iOS Kindle app. Nope. “Reader apps” fall under a different guideline – 3.1.3(a) – which doesn’t have the same IAP requirement that 3.1.3(b) has.

6/ That said, it seems like it might be tough (and time consuming) for App Review to investigate and judge whether an app is or isn’t multi-platform. I anticipate that lots of apps that are iOS-only will slide through.

5/ Additionally, 3.1.3(b) is very clear that it applies only to “apps that operate across multiple platforms.” Apps that are iOS-only need not apply. They don’t qualify to sell features through their website.

3/ Realize that guideline 3.1.3(b) cuts both ways. It will be a great option for some apps, but there have been some SaaS that have gotten a “free companion app” on the App Store that requires a subscription that is only available on the SaaS’s website.
